A Brendon Santalab winner at the death secured Western Sydney their first home A-League derby victory over Sydney FC at Parramatta Stadium on Saturday night.

Santalab, who came on as a substitute for striker Tomi Juric on the hour, scored the winner in the 87th minute to ensure the triumph over their cross-town rivals in what was a real arm wrestle played at a frenetic pace.

In the previous four derbies, surprisingly the Wanderers have won both clashes at Allianz Stadium but were yet to record a derby win in front of their own fans.

Fans turned out in numbers to watch the clash with over 18,000 filling the stands.

And while the contest may have been heated on the pitch, the supporters were well behaved during the match with Football Federation Australia to impose a three-point deduction on the Wanderers should their fans not toe the line.

The Wanderers, who suffered their first home loss in 12 months to lowly Wellington last week, came out with a point to prove and were on the attack from the get go.
